#### Question

Following number line shows the temperature in degree celsius (°C) at different places on a particular day.

Can we say temperature of Srinagar and Shimla taken together is less than the temperature at Shimla? Is it also less than the temperature at Srinagar?

#### Solution

Temperature at Srinagar = −2°C

Temperature at Shimla = 5°C

Temperature of Srinagar and Shimla taken together = −2°C + 5°C

= 3°C

3°C < 5°C

3°C < Temperature of Shimla

Yes, the temperature of Srinagar and Shimla taken together is less than the temperature of Shimla.

However, 3°C > −2°C

Hence, the temperature of Srinagar and Shimla taken together is not less than the temperature of Srinagar.

Is there an error in this question or solution?
